Abstract

Ammortizzatore regolabile per autoveicoli con un cilindro contenente un liquido ammortizzatore, un'asta di pistone, che penetra in esso ermeticamente ed è disposta scorrevole assialmente, e con un pistone ammortizzatore che è fissato ad essa e suddivide il cilindro in due spazi di lavoro, laddove la valvola ammortizzatrice, dotata di un corpo valvolare movibile assialmente e di una sede valvolare, comanda la sezione trasversale attiva di un canale ammortizzatore. Il corpo valvolare a tale scopo, partendo dalla sua superficie frontale sollecitata a pressione presenta almeno un foro di strozzatura costante, estendentesi verso il lato posteriore contrapposto, ed un foro di strozzatura, che si estende dal lato posteriore in direzione di deflusso del canale ammortizzatore viene comandato da un elemento di. precomando scorrevole continuamente assialmente, laddove l'elemento di precomandoAdjustable shock absorber for motor vehicles with a cylinder containing a shock absorber liquid, a piston rod, which penetrates it hermetically and is arranged axially sliding, and with a shock absorber piston which is fixed to it and divides the cylinder into two working spaces, where the shock absorber valve, equipped with an axially movable valve body and a valve seat, controls the active cross section of a shock absorber channel. The valve body for this purpose, starting from its pressure-stressed front surface, has at least one constant constriction hole, extending towards the opposite rear side, and a constriction hole, which extends from the rear side in the direction of outflow of the shock absorber channel. controlled by an element of. pre-control sliding axially continuously, where the pre-control element
